Goldfish reach an inch when they're at least 4-5 weeks. They tend to grow incredibly fast at first especially when they are kept in tubs with plenty of plants. Beware of where you are getting your plants. I lost hundreds of my goldfish fry to dragonfly nymphs!
Please reconsider breeding if you are lacking enough space because these are definitely going to take up a lot of filtration and water changes with plenty of wastes produced. Do not expect all the fry to survive adulthood. On the other hand, it would be much better if you focus on half a dozen fry to raise with than deal with hundreds of stunted fish. Quality over quantity.
Males should have white pustules showing up around the gill covers and first ray of pectoral fins. Be able to familiarize yourself with that since this breeding sign is often confused with the actual white spot disease resulting in aquarists unnecessarily dumping meds into their tanks and killing their perfectly healthy fish. Females tend to get rounder when they start to spawn.
Also, pearlscales do grow bigger than 2 inches. The largest I've seen is 8 inches. Not a common occurrence but it still happens. If you want to breed them, be sure to breed them at their adult stage/size and not while they are young. Pearlies that are able to breed at 2 inches and smaller are most likely stunted. They do not reach sexual maturity until a year.
As goldfish are egg scatterers, I only used floating plants and balls of yarns to do the job. Eggs stick around there like adhesives. They usually spawn in the dawn so be on guard for that. Once they are done fertilizing their eggs, immediately remove the spawning mops with eggs sticking and place them inside another tank with extremely clean water. Leave the rest of the eggs sticking on glass and elsewhere to be served as food for the fish since it's no use removing them with razors. Do a large water change as well to help dilute any resulting foul odor from infertile eggs. Infertile eggs stink a lot and can cause stress on your fish even killing them. A 3-inch goldfish can produce thousands of eggs (though again, with the exception of Siamese dolls, these are still STUNTED).
Hope this helps.
